Description

[0001] Side frame and drawer

[0002] The present invention relates to a side frame according to the preamble of claim 1 and a drawer.

[0003] WO 2020 / 182583 A1 discloses a side frame of this type. A decorative wall element can be secured to this frame by means of a fastening means comprising an adhesive strip in a lower region of the wall element. The lower region of the side frame is bent to increase the strength of the wall element. However, the bent edge is relatively difficult to manufacture.

[0004] It is therefore an object of the present invention to provide an improved wall element for a side frame of a drawer.

[0005] The present invention solves this problem with a side frame having the features of claim 1 and a drawer having the features of claim 23.

[0006] According to claim 1, a side frame for a drawer is provided with a first and a second wall element, with

[0007] - a first and a second wall element forming a housing in the form of a hollow chamber with two outer walls,

[0008] - a holder for a drawer base,

[0009] - a third wall element for covering at least part of the housing, wherein the third wall element is reversibly fastened to the housing by means of a fastening element having a thickness M,

[0010] - wherein the third wall element comprises a bent sheet with a material thickness D, which has a first plate-shaped portion and a second portion aligned at an angle to the plate-shaped portion, such that the third wall element is adapted to the shape of at least part of the housing by means of the second portion, and

[0011] - wherein the first plate-shaped section has an envelope formed from the sheet metal along at least one side,

[0012] - where the material thickness D of the sheet is equal to or less than the thickness M of the fastener, and where twice the material thickness D of the sheet is greater than the thickness (M) of the fastener. Therefore, D<= M and 2D>M.

[0013] The third wall element thus forms a simple, easily installed designer cover. It allows for a visually appealing cover for the frame without compromising its technical functionality. The third wall element is also easy to manufacture and, thanks to its at least one fold in its area, offers high stability.

[0014] In the context of the present invention, the term "fold" in the present specification, in the sense of forming technology, means that it has been formed by a bending process comprising at least two stages. In such a bending process, the sheet metal was preferably pre-bent with an opening angle of preferably more than 15° and then pressed together at least once to form a fold. To ensure it can be easily manufactured, the fold is higher perpendicular to the bending line than a simple edge bend - in particular at least 3 mm high. This means that in the area of ​​the fold, starting from a bending radius, material sections lie completely or essentially flat against one another. The respective material section is thus doubled in the area of ​​the fold.

[0015] The approximate circular arc formed by the turn-up or advantageous radius of the sheet preferably comprises a radian measure of approximately TT radians, which in the angular measure of the circular arc leads, for example, to an angle - measured around the turn-up - of approximately 175° to 185° between the plate-shaped section of the wall element and the section of the sheet on the other side of the turn-up, whereby the wall element is particularly stable.

[0016] According to a first preferred embodiment, it is provided that the first plate-shaped section of the third wall element has at least one magnetic element or several magnetic elements as the at least one fastening element.

[0017] This enables simple and damage-free, repeatable disassembly and assembly of the wall element, for example, on the housing of the side frame. The at least one magnetic element is particularly preferably arranged along the first fold, in particular on the plate-shaped section, in order to mount the wall element as close as possible to the housing of the side frame for space-saving installation. According to one possible embodiment, one or more of the first magnetic elements can be advantageously and simply arranged in a straight row along the first fold on the plate-shaped section.

[0018] According to a further preferred embodiment, the at least one first magnetic element can be arranged above the first cover at a distance from it. At this point, it can be particularly easily integrated into the structure without negatively affecting the dimensions of the frame.

[0019] According to a further preferred embodiment, it can be provided that the folds have a fold thickness Ud which essentially corresponds to twice the material thickness D of the sheet.

[0020] According to a further preferred embodiment, the third wall element can be provided on the second section—preferably on its side facing downwards in the installed state—with at least one second magnetic element or several second magnetic elements as the at least one fastening element. This magnetic element or these magnetic elements improves the fit of the third wall element in a simple manner, since it is thus secured on two different sides in the installed state.

[0021] In particular, a material thickness of the plate-shaped section or of the sheet metal is lower than that of the at least one magnetic element for a particularly advantageous arrangement.

[0022] The respective first and second magnetic elements can thus in turn be constructed from several individual magnetic elements or can each be composed as a single long magnetic strip.

[0023] According to a further preferred embodiment, it can be provided that the at least one fastening element is connected in a materially bonded manner, in particular by gluing, to the first plate-shaped section or the second section, so that it can be easily removed from the side frame together with the sheet metal.

[0024] According to a further preferred embodiment, the third wall element can be made essentially of aluminum or an aluminum alloy, and the first and second wall elements can be made of sheet steel. Due to its ease of processing and low weight, the wall element is particularly preferably made of aluminum or an aluminum alloy.

[0025] The magnetic element is preferably glued to the third wall element if the third wall element is made of aluminum or an aluminum alloy. This ensures that the magnetic element remains securely attached to the third wall element during disassembly without magnetically adhering to it. However, the third wall element can also be made of a different material, for example, sheet steel.

[0026] According to a further preferred embodiment, it can be provided that the first turn and the second turn of the wall element have a turn height, wherein the turn height of the first turn is greater than the turn height of the second turn.

[0027] According to a further preferred embodiment, the first and / or second fold of the wall element can have a fold height of 3 mm, preferably of up to 10 mm to 20 mm. With such a minimum height of 3 mm, preferably in the range of up to 10 mm to 20 mm, the aforementioned fold can be manufactured particularly well.

[0028] According to a further preferred embodiment variant, which promotes a stable and compact construction of the frame, it can be provided that the turns form a turn-over surface, wherein the turn-over surface formed by the second turn-over has a smaller area than the turn-over surface formed by the first turn-over.

[0029] The sheet metal can have a thin material thickness of preferably 0.4 mm to 0.8 mm. In a preferred embodiment, it has a material thickness of 0.5 mm ± 0.05 mm, allowing it to be designed particularly thinly or with minimal material consumption. The at least one magnetic element is then preferably designed to be only slightly thicker or the same thickness as the sheet metal in this direction.

[0030] According to a further preferred embodiment, it can be provided that the bent sheet metal of the third wall element has an L-shaped cross-section, so that the housing is advantageously completely or partially covered at the top and on one of the outer walls. According to a further preferred embodiment, it can be provided that the bent sheet metal of the third wall element has a U-shaped cross-section with preferably differently long legs, so that the housing is enclosed in a U-shape in the upper region and is further covered on one of the outer walls. In this variant, too, the upper region of the wall element is stable and visually appealing, so that it can securely cover the frame even in the vertically upper region.

[0031] According to a further preferred embodiment, the first plate-shaped section can have a second fold along at least one further side or side edge. This is another advantageously producible and stable—but not absolutely necessary—configuration. However, the second section can also be designed in a different way to ensure sufficient stability and ease of manufacture.

[0032] According to a further preferred embodiment, it can be provided that all, or at least the outer areas or walls of the first and second wall elements facing outward relative to the hollow chamber in the assembled state, have a powder coating and / or the third wall element has a foil coating. Alternatively, the third wall element can have a painted surface, which can inhibit corrosion of the wall element and lead to a particularly long service life. Furthermore, this also results in a particularly advantageous appearance of the side frame.

[0033] According to a further preferred embodiment, it can be provided that the first envelope is arranged substantially parallel and at a distance at least partially next to the first or second wall element.

[0034] The magnetic element preferably comprises at least two layers, with a first layer facing the second wall element being formed by a magnetic strip and a second layer facing the third wall element being formed by an adhesive layer. The sum of the thicknesses of all layers of the magnetic element corresponds to the thickness of the fastening element. This makes it particularly easy to fix the magnetic element to the third wall element.

[0035] In particular, the magnetic element is made of an extruded plastic with a magnetic material for a simple and cost-effective design.

[0036] According to a further preferred embodiment, it can be provided that the magnetic permeability p r of the third wall element is smaller than the magnetic permeability p ron the wall element to which the at least one magnetic element is attached. This enables particularly simple installation of the side frame and simultaneously reduces unwanted magnetization of any objects located in the vicinity of the side frame.

[0037] According to a further preferred embodiment, it can be provided that the second section has a second fold of the bent sheet along one side.

[0038] According to a further embodiment, the first cover, when mounted on the frame, can be arranged substantially parallel and at a small distance at least partially next to the first or second wall element.

[0039] The invention also provides an advantageously designed drawer with a base, a front panel, a rear wall and two side frames according to one of claims 1 to 22.

[0040] The present invention is explained in more detail below using exemplary embodiments shown in several drawings. The invention is not limited to the exemplary embodiments shown, but can also be implemented in other ways within the scope of the claims. Individual features of the exemplary embodiments described here are also advantageous in themselves. This means that they do not necessarily have to be used together as shown, but can also be combined in other ways in other exemplary embodiments (not shown). They show:

[0041] Fig. 1a and 1b two different views of a wall element for a frame,

[0042] Fig. 2a and 2b views of a wall element according to a further embodiment,

[0043] Fig. 3a and 3b an extended embodiment of the wall element from Fig. 1 ,

[0044] Fig. 4a to 4c in a) and b) an extended embodiment of the wall element from Fig. 2, and in c) a representation of the magnetic element,

[0045] Fig. 5a and 5b in a) a cross section of a drawer according to the invention with a side frame according to the invention according to Fig. 2a and in b) an enlarged detail from Fig. 5a, Fig. 6 a cross section of a side frame according to the invention with a wall element according to Fig. 1,

[0046] Fig. 7 shows a cross-section of a side frame according to the invention with a wall element according to Fig. 2, and

[0047] Fig. 8a to 8g several views of a side frame according to the invention.

[0048] Fig. 1 shows in a) a Cartesian coordinate system X, Y, Z. In the usual installation position, the Z direction corresponds to a vertical direction and the X direction and the Y direction define a horizontal plane, whereby the X direction can correspond to a pull-out direction of the drawer.

[0049] Fig. 1a shows an isometric view of a third wall element 1 of a side frame according to the invention (not shown). The third wall element 1 comprises a bent sheet metal forming a first plate-shaped section 2 and a second section 3. The second section 3 is angled approximately perpendicular to the plate-shaped section 2. The third wall element 1 can thus have a substantially L-shaped cross-section. This can be expanded into a U (this will be described in more detail below).

[0050] The plate-shaped section 2 has a first turn 4 of approximately 175° to 185° in a lower region of the third wall element 1 corresponding to Figure 1a. The third wall element 1 can also have a further optional second turn 5 in the region of the second section 3, which can also extend over approximately 175° to 185°.

[0051] As a result, the material, i.e. the bent sheet, is bent and folded at these points in such a way that the respective material sections, as can also be seen in Fig. 1 b, i.e. for example the first plate-shaped section 2 and the turn-up surface 6 and / or the second section 3, with the turn-up surface 7 on both sides of the turn-up 4, 5 lie completely or at least substantially flush with one another.

[0052] The approximate radius formed by the turns 4 or 5 thus comprises a radian measure of approximately TT radians, which in the angular measure of the circular arc results in an angle of approximately 175° to 185°.

[0053] The wall element 1 thus formed is easy to manufacture and very stable in the area of ​​the turn-up with its radius. Figs. 2a and 2b show a further embodiment of the third wall element 1, which essentially has a cross-section roughly corresponding to a U with unequal longitudinal legs, i.e. roughly a J. The second section 3 has a further bend of approximately 90°, as can be seen in particular in Fig. 2b. In an alternative, preferred variant, it can also be provided that the third wall element 1 does not have the second, upper turn-up 5.

[0054] Fig. 3a shows an isometric view of the third wall element 1 from Fig. 1a, wherein at least one magnetic element 8 is arranged on the plate-shaped section 2 and optionally fixed thereto in a materially bonded manner, in particular adhesively. In the variant shown, three of the magnetic elements 8 are provided.

[0055] As can be seen from Fig. 3b, alternatively or additionally at least one second magnetic element 9 can be arranged on the second section 3 and optionally fixed thereto in a materially bonded manner, in particular adhesively, particularly preferably between the cover surface 7 and the plate-shaped section 2 on the underside of the second section 3.

[0056] The views of Figs. 4a and 4b correspond essentially to Figs. 3a and 3b, wherein the third wall element 1 shown is the third wall element 1 from Fig. 2 with the modified cross section.

[0057] The third wall element 1, i.e. in particular the sheet metal and / or the first plate-shaped section 2 and / or the second section 3, preferably has a material thickness D of 0.4 mm ± 0.05 mm to 0.8 mm ± 0.05 mm, for example 0.5 mm ± 0.05 mm. The at least one magnetic element 8 or the at least one second magnetic element 9 preferably have a material thickness of 0.45 mm ± 0.05 mm to 0.85 mm ± 0.05, in particular 0.55 mm ± 0.05 mm. The magnetic elements 8, 9 can preferably be designed as magnetic strips.

[0058] Preferably, the material thickness D of the sheet is less than or equal to the thickness M of the fastening element and twice the material thickness 2*D of the sheet is greater than the thickness M of the fastening element.

[0059] The following applies (for all configurations shown):

[0060] D<= M and 2D >M (See Fig. 4b) .

[0061] In the area of ​​the folds 4, 5, the material thickness D results in a fold thickness Ud of at least twice the material thickness D (see Fig. 3b). Due to the elastic properties of the sheet, the fold thickness Ud may be slightly greater than twice the material thickness D. The thickness M is preferably (preferably slightly, taking tolerances into account) greater than half the fold thickness Ud.

[0062] The first cover 4 can then be arranged essentially parallel and at a distance A at least partially next to the first or next to the second wall element 11, 12.

[0063] As can be seen, the selected dimensions of the cover 4 and the magnetic elements 8 allow a gap A between the side frame and the wall element 1 in the area of ​​the cover 4 to be kept small, so that it is no longer or hardly visible.

[0064] According to one possible embodiment, the turn-up 4 or the turn-up surface 6 can have a turn-up height H (here in the vertical direction or Z direction perpendicular to the main extension direction X of the frame in the horizontal direction) of a few mm, for example 3 mm to 20 mm, in particular 10 mm to 20 mm, starting from the outer radius. The optional turn-up surface 7 on the second section 3 can also have a corresponding turn-up height h of the turn-up 5. These dimensions can also be used in particular in the variants of Figs. 1a to 4b and in other variants according to the invention not shown. As can be seen in Figs. 1a to 4b, the dimensions of the turn-up height H, h can be selected such that the turn-up height H on the first turn-up 4 is greater than the turn-up height h on the second turn-up 5. However, they can also be the same. It is preferably greater than 3 mm in each case to ensure good manufacturability.

[0065] Fig. 4c shows an enlarged cross-section of the magnetic element 8 from Fig. 4b. The thickness M of the magnetic element 8 is less than twice the material thickness D of the third wall element 1 and essentially corresponds to the material thickness D of the third wall element.

[0066] Fig. 5a shows a cross-section of a drawer according to the invention with two side frames 16 according to the invention, one of which is visible in the figure. Fig. 5b shows an enlarged view of a portion of the side frame 16 from Fig. 5a. The side frame 16 comprises a first wall element 11 and a second wall element 12, which form a housing of the side frame 16 with outer walls.

[0067] The side frame 16 is fixed to a drawer base 10 arranged in a receptacle 14 of the first wall element 11. It optionally further comprises a connecting interface 13 for a drawer pull-out guide (not shown here). A third wall element 1 according to the invention, as shown in Fig. 4a, is arranged on the housing of the side frame, although one of the third wall elements 1 from Figs. 1a to 3b could alternatively be used. In the area of ​​the first fold 4, the third wall element 1 from Fig. 5a has the fold thickness Ud.

[0068] The second section 3 in Figs. 5a and 5b is adapted to the shape of the housing of the side frame 16. The first and second magnetic elements 8 and 9 additionally fix the third wall element 1 to the side frame 16. It is evident that the adapted shape in this embodiment gives the upper side frame contour a new shape or an improved external design. It is not necessary for the adapted shape to exactly reflect the contour of the side frame 16. For example, a view with sections aligned at right angles to one another in a desired appearance (e.g., surfaces made of brushed aluminum, etc.) is preferred.

[0069] In Fig. 5b, it can be clearly seen that the folded surface 6, which is directed toward the second wall element 12, does not abut the second wall element 12 in the assembled state, but rather, taking all tolerances into account, preferably still has a distance A from it. The distance A lies in a range of less than 0.3 mm and can also be 0 mm.

[0070] Fig. 6 shows a cross section of a side frame 16 according to the invention with a third wall element 1 which is L-shaped in cross section and which is designed in the manner of Fig.

[0071] I and which is attached to the housing of the side frame 16, which is composed of the first wall element 11 and the second wall element 12, by means of the magnetic elements 8. The advantageous covering of the frame 16 upwards and, relative to the interior or bottom of the corresponding drawer, preferably outwards, can be clearly seen.

[0072] Fig. 7 shows a cross section of a side frame 16 according to the invention with a third wall element 1 according to the type of Fig. 2, which is fixed by means of the second section to the housing of the side frame 16, which consists of the first wall element

[0073] II and the second wall element 12. The bent sheet metal of the third wall element 1 has a U-shaped cross-section with a transverse leg and longitudinal legs of different lengths, so that the housing is advantageously U-shaped in the upper region and is preferably further covered towards the outside relative to the interior or bottom of the corresponding drawer. In both embodiments of Figs. 6 and 7, a gap-like intermediate space can be formed between the housing of the side frame 16 and the wall element 1, preferably by means of the cover surfaces 6 and / or 7.

[0074] Fig. 8a-g illustrates the structure of an exemplary frame (still) without the (designer) wall element 1. As shown, a support element 15 for functional devices such as a front panel fastening device can be arranged and fixed in the hollow channel-like housing, in particular between the first wall element 11 and the second wall element 12. The easily manufactured (designer) wall element forms a visually appealing partial cover for the frame 16, which is easy to install and does not impair the functionality of the frame 16 from a technical perspective.

[0075] The magnetic element 8 consists of at least two layers. The first layer is a magnetic tape and the second layer is an adhesive layer. The magnetic tape can be an extruded plastic with a magnetic or magnetizable material. The adhesive layer can be applied as an adhesive layer or also in the form of double-sided adhesive tape. The magnetic element 8, including all layers, forms the thickness M. The material thickness D of the third wall element 1 is equal to or less than the thickness M of the magnetic element, including all layers, and twice the material thickness D of the third wall element 1 is greater than the thickness M of the magnetic element, including all layers.
